Answer:
y = - 4
Step-by-step explanation:
Given
y = 2x + ( - 2) , that is
y = 2x - 2 ← substitute x = - 1
y = 2(- 1) - 2 = - 2 - 2 = - 4
This is confirmed by the point (- 1, - 4 ) on the graph
May someone please help me with this :)

Step-by-step explanation:
Found the cube root of 1331
[tex] \sqrt[3]{1331} = 11[/tex]
Reciprocal of 0.2 is
[tex] \frac{1}{0.2} = 5[/tex]
Our ratio is 11:5. Our right hand number must equal 1 so we divide 5 by both sides.
[tex]11 \div 5 = 2.2[/tex]
So our n is 2.2

A pizza parlor sells pizza in two sizes, a 16 inch pizza or a 10inch pizza. Which is more pizza, half of the 16-inch pizza or the entire inch pizza?
Topic: arc length and sector area
Answer:
Therefore the second pizza of 10inch is More
Y>X
Step-by-step explanation:
From the question we are told that:
Diameter of pizzas
Pizza one [tex]D_1=16[/tex]
Pizza two [tex]D_2=10[/tex]
Generally the equation for amount of half of pizza one X is mathematically given by
[tex]X=\frac{1}{2}\pi r^2[/tex]
[tex]X=\frac{1}{2}\pi 8^2[/tex]
[tex]X=100.53inch^2[/tex]
Generally the equation for amount of pizza two Y is mathematically given by
[tex]Y=\pi r^2[/tex]
[tex]Y=\pi 10^2[/tex]
[tex]Y=314.16inch^2[/tex]
Therefore the second pizza of 10inch is More
Y>X

land on tails and the other coin will land on heads?
Answer:
the probability is 0.25
Step-by-step explanation:
first flip if head:0.5
second flip after head:0.5 each
first flip if tails:0.5
second flip after tails:0.5 each
0.5 x 0.5 = 0.25
Hello, can you help me please
Step-by-step explanation:
1. C(x) is in vertex form so let write the function out.
[tex]a(x - 1) {}^{2} + b[/tex]
B is our maximum value so b=9.
[tex]a(x - 1) { }^{2} + 9[/tex]
To find a, we know that when x=5 is a root so plug 5 in for x to find a.
[tex]a(5 - 1) {}^{2} + 9 = 0[/tex]
[tex]a(4) {}^{2} + 9 = 0[/tex]
[tex]16a = - 9[/tex]
[tex]a = - \frac{9}{16} [/tex]
2.. Let convert Chelesa function into. standard form.
[tex] \frac{ -9 }{16} (x - 1) {}^{2} + 9[/tex]
[tex] - \frac{9}{16} (x {}^{2} - 2x + 1) + 9[/tex]
[tex] - \frac{9}{16} {x}^{2} + \frac{9}{8} x + \frac{135}{16} [/tex]
Let see which value has the higher constant.
135/16 is more than 8 so Chelsea jumper higher.
3. Set Herritea equation equal to zero.
[tex] - \frac{2}{9} {x }^{2} + 8 = 0[/tex]
[tex] - \frac{2}{9} x {}^{2} = - 8[/tex]
Multiply both sides by the reciprocal of negative 2/9.
[tex] {x}^{2} = - 8 \times - \frac{9}{2} [/tex]
[tex] {x}^{2} = 36[/tex]
[tex]x = 6[/tex]

On a certain hot summer's day, 335 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $619.2. How many children and how many adults swam at the public pool that day?
Answer:
57
Step-by-step explanation:
Let c represent the number of children ($1.75 each) and a represent the number of adults ( $2.00 each).
We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c
We also know that $1.75 c + $2.00 a = $609.25
By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25
Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25
Subtract $680 from both sides and combine like terms to get - $0.25 c = -
$70.75
Now, divide both sides by -$0.25 to get c = 283, the number of children.
The number of adults is 340 - c or 340 - 283 = 57

Answer:
x=9
Step-by-step explanation:
Since, these angles are identified as vertical angles, both sides are equal to each other. So, in order to solve this problem, we have to set the equations equal to each other: (7x+3 = 10x-24).
A circle is inscribed in a square with a side length of 144. If a point in the square is chosen at random, what is the probability that the point is inside the circle?
Given :
A circle is inscribed in a square with a side length of 144.
So, radius of circle, r = 144/2 = 72 units.
To Find :
The probability that the point is inside the circle.
Solution :
Area of circle,
[tex]A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2[/tex]
Area of square,
[tex]A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2[/tex]
Now, probability is given by :
[tex]P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785[/tex]
Therefore, the probability that the point is inside the circle is 0.785 .

Answer:
x = 24
Step-by-step explanation:
To simplify the work we can use the Pytaghoran theorem in this way:
x^2 + x^2 = (24√2)^2
2x^2 = 24^2 *(√2)^2
2x^2 = 576 * 2
x^2 = 576
x = +/- √576
x = +/- 24
we choose only the positive value because a length can’t be negative
x = 24
Find the measure of the indicated arc
Answer:
m(arc WXY) = 224°
Step-by-step explanation:
By inscribed angle theorem,,
"Measure of intercepted arc is double of the inscribed angle"
m(arc WXY) = 2[m(∠YCW)]
Here, arc WXY is the intercepted arc and ∠YCW is the inscribed angle.
By substituting the value of inscribed angle,
m(arc WXY) = 2(112°)
= 224°
Therefore, measure of arc WXY is 224°.

O B. y = 4(x - 2)2 +1
O C. x = 4(y - 1)2 - 2
O D. y = 4(x - 2)2 - 1
Answer:
y = 4(x + 2)^2 + 1 (Answer B)
Step-by-step explanation:
Here we're given h = -2 and k = 1. Right away we know that the vertex form of the pertinent equation is
y = 4(x + 2)^2 + 1 (Answer B)
Factor completely:
3x2 - 75
Answer:
3(x + 5)(x − 5)
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula:
a² − b² = (a + b)
(a − b)
where a = x and b = 5.
3(x + 5)(x − 5)

Terry has 15 candles. She needs at least 100 candles. The candles she wants are sold in boxes of 8.
What is the least number of boxes of 8 candles that Terry needs to buy?
Answer:
11 boxes of candles
Step-by-step explanation:
first, set it up as an equation. let x stand for the amount of boxes she needs.
100=8x+15
next, subtract 15 from both sides of the equation.
100-15=8x+15-15
85=8x
then, you need to get x by itself. to do this, divide 8 from both sides of the equation.
85/8=8x/8
x=10.62, but you can't buy half a box, so you have to round up.
so, she needs to buy 11 boxes of candles.
